The HI96707 is an auto diagnostic portable microprocessor meter that benefits from Hanna
Instruments’ years of experience as a manufacturer of analytical instruments. It has the advanced
optical system based on a special Tungsten Lamp and a narrow band interference filter that allows
most accurate and repeatable readings. All instruments are factory calibrated and the electronic
and optical design minimizes the need of frequent calibration.
With the powerful

validation function, you are able to validate good performance
of your instrument at any time. The validation procedure is extremely user friendly. Just use the
exclusive Hanna Instruments ready‑made, NIST traceable standards to verify the performance of
the instrument and recalibrate if necessary.
All instruments are splash proof and the lamp and filter units are protected from dust or dirt by
a transparent cup. This makes the instruments fulfill field applications. Display messages aid the
user in routine operation. The meter has an auto‑shut off feature that will turn off the instrument
after 10 minutes of non use in measurement mode or after 1 hour if left in calibration mode.
The meter uses an exclusive positive‑locking system to ensure that the cuvette is in the same
position every time it is placed into the measurement cell. It is designed to fit a cuvette with a
larger neck making it easier to add both sample and reagents. The cuvette is made from special
optical glass to obtain best results.
The
HI96707 meter measures the Nitrogen‑Nitrite (N0

‑N) content in the samples in the 0.000
to 0.600mg/L (ppm) range, in drinking, surface and saline water samples and in domestic and
industrial wastes. The method is an adaptation of an EPA approved method.
The reagent is in
powder form and it is supplied in packets. The amount of reagent is precisely
dosed to ensure the maximum repeatability.
